I live in the Himalayas in India. I would like to know the performance of Vance Delicious on MM 111 rootstock and that of Wellspur on M4 rootstock.

Wellspur and Vance both spur red delicious type apples are both classified as medium vigor, T2, apples. This indicates that the trees should be on the small side of the indicated size given. Data indicates that M.4 woould be more productive than M.111.

MM.111, EMLA MM.111

Size: 30 to 34 feet (EMLA MM.111 will be slightly larger than MM.111) (75 to 85% of standard)

Observations, suspicions, and history:
â€¢ MM.111 is appropriate for use with spur type scion varieties, on poor dry sandy soils, and on heavy soils where MM.106 would fail.
â€¢ One of most drought resistant apple rootstock known.
â€¢ Because MM.111 produces large trees, utility of MM.111 in North America is limited to extreme situations and home gardens.
â€¢ MM.111 is very tolerant of a wide range of soil conditions, and is the most drought tolerant clonal produced apple rootstock.
â€¢ MM.111 is used as rootstock with an M.9 interstem to produce dwarf freestanding trees that are drought tolerant.
â€¢ Tolerant of both heavy and light soils.
â€¢ Planting distance, suggested, 15 ft (4.5m) apart, 20 ft (6m) between rows.

I do not know much about M.4 but here is some information from internet.
M.4 -- Size: 80-85%. One of the most productive of the vigorous rootstocks. While the roots produce a well anchored base, the tree has been known to lean for certain varieties. It is adaptive to most soil types, resistant to crown rot, and tolerant of fire blight. It is moderately winter hardy.
